Last week I found myself pursuing five electric scooters at ten miles per hour that had commandeered a full traffic lane northbound in Denver on Lincoln Avenue. Since Bird and Lime dumped hundreds of their stand-up, motorized scooters without warning on the city’s sidewalks, more and more riders seem to feel the street is a better option for them than the sidewalk. This can’t possibly be a good idea and it is only a question of time before a driver dispatches several of them to an emergency room or the morgue. Skateboarders are now joining in the fun. Honking at them only elicits a middle-fingered salute.
